摘要

We consider a construction of a family of almost-sharp fronts for the Surface Quasi-Geostrophic equation. The family is indexed by a parameter indicating the thickness of the almost-sharp front. In this paper we obtain the limit equation when the parameter approaches zero and construct approximate solutions of SQG in the analytic class.
